Abstract
Y ions incorporation effect on structural, ferroelectric and ferromagnetic properties of Bi$_{1-x}$Dy$_x$FeO$_3$ (x = 0.00, 0.05, 0.10, 0.15 and 0.20) has been elaborated by solid-state reaction method. The beam of Y ions (500 keV) at a fluence of 3 ${\times}$ 10$^{12}$ ions cm$^{-2}$ was exposed in studied samples. The X-ray diffraction technique and Rietveld refinement indicate the rhombohedral polycrystalline structure. The FESEMx analysis show dense grains uniformly distributed on sample surface and decrease in grain size by decreasing the Dy concentration. The bonding nature and chemical composition have been studied by X-ray photoelectron spectroscopy. The coexistence of ferromagnetic and ferroelectric orderings has been observed at room temperature. The polarization (10.50 ${\mu}$C cm$^{-2}$) and ferromagnetism is maximum at 15% Dy concentration and decreases with further increase in Dy contents.
